In addition to this list the "Special oils" Busch sheet can be used.
VM100
DILO order No.: 3-690-R201 / 3-690-R203
Ambient temperature: 5 - 30 °C Lubricant recommended by Busch: VM 100
VM 100 is a mineral oil and corresponds to the VC in accordance with DIN 51506. The viscosity class is
ISO VG 100 according to DIN 51 519.
ISO VG 100: specific gravity at +15 °C 0.897 g/cm

cinematic viscosity at 40 °C 112.0 mm
2
/s (cSt)
cinematic viscosity at 100 °C 11.5 mm
2
/s (cSt)
flashpoint 255.0 °C
pour-point -12.0 °C
This viscosity corresponds to an oil of the SAE 30 class in accordance with DIN 51511.
Examples for VM 100 lubricants:
Aral: Motanol 100 Avia: Avialup VD-L 100
BP: Energol CS 100 / RC-S 100 Mobil Rarus 427
Texaco: Ursa-Öl P 100 Servo Delben: Anderol 500
Schell: Talpa-Öl G 100 / Corena P 100 Esso: Umlauföl 100
VS100/VSL100
DILO order No.: 3-690-R212
Ambient temperature: > 30 °C Lubricant recommended by Busch: VS 100
VS 100 is a synthetic oil and corresponds to the VC in accordance with DIN 51506. The viscosity class is
ISO VG 100 according to DIN 51 519.

/s (cSt)
flash point 265,0 °C
pour-point -48,0 °C
This viscosity corresponds to an oil of the SAE 30 class in accordance with the DIN 51511. This oil is
particularly used in case of higher suction temperatures or an ambient temperature exceeding +40°C
due to its good thermal properties.
Examples for lubricants VS 100:
BP: Enersyn RC-S 100 Mobil Rarus 827
Esso: Compressor Oil RS 32-68 Shell: Cassida Fluid VP 100
